Winter formal!!

Traci

So my college is having a winter formal and I wanted to know if this looks good or if I should find something a little more fancy. It’s at a casino and you are allowed to go gamble as long as you’re 18+ and my boyfriend and his best friend who is also one of my best friends wanna go and gamble for part of the formal. I am going to tag along because why not. I just really wanted to have opinions on this matter because I don’t know.
